On all Motifs, the basic sound element is a sample. This is a one-shot
recording (like a drum sound), or a single note on an instrument (like a C
played on a piano).
The Motif doesn't play samples directly. Instead, the Motif combines
individual samples into waveforms. You can have a waveform that contains a
single sample that is mapped all of the way across the keyboard (like a drum
sound that plays higher or lower as you play along the keyboard), or a complex
waveform (such as a piano that uses a different sample for each key). The
samples that are contained in a waveform, and the key ranges that trigger that
sample are described by what is called a keybank.
So, to recap, its like this.
Waveforms contain one or more keybanks. Each keybank references a sample, and
indicates the range across the keyboard or a range of velocities that will
trigger it.
Usually, when you load a sample into the Motif, the Motif will start a new
waveform for you, will create one keybank inside that waveform, will set the
keybank to play your loaded sample, and will map that keybank so that it is
triggered by all keys and all velocity ranges.
If you want to edit waveforms, you have to use the sample mode on the Motif.
Once you have built a waveform, you can use John's editors to create voices
from them.
To make this clearer, here is an example. Suppose we want to make our own
voice that plays a piano together with strings. We want to use the built-in
string sound, but we'd like our own piano.
For our basic piano, we aren't going to record each note. Instead, we decide
to record each C (from the bottom C to the top C). That gives us 6 Cs, I think.
Then, we load these 6 recordings of C played in each octave into the Motif.
Now, we make a new waveform. We create 6 keybanks, and we map each of our 6
samples to these 6 keybanks. We set the root note of each of the keybanks to
the same note that was recorded on the piano. Now, when we play middle C, we
hear the same middle C that we recorded on the piano. When we play the C above
middle C, we hear the appropriate recording, also. When we play the notes
in-between, though, we hear nothing. That's because we didn't record samples
for every key. To deal with that, we can set the keybank for middle C so that,
instead of being triggered only when we play middle C on the Motif, it will be
triggered by everything from the A flat below middle C up to the G above middle
C. We don't have samples for those notes, but what the Motif will do is to
pitch middle C down or up to play the appropriate pitch. We repeat this
stretching for each of the 6 keybanks. When we're finished, we can play all
across the keyboard, and the Motif will play the sample with the nearest pitch
to the note that we're playing. All of these settings make up a waveform, and
we make them all in the Sampling mode. One odd thing though, while we'd hear
the correct samples at this point, they won't exactly play like a piano. As
soon as we let go of a key, the sound will immediately cut off with out even a
brief decay. Playing hard or sof on the keyboard will produce a louder or
softer tone, but only in terms of volume (the soft notes won't seem dulled
out). This is because all of that is handled by synthesis. In sample mode,
we're just mapping samples to keys.
Now that we have a waveform that triggers appropriate samples to play a
piano, we can make a voice out of it. Here, we can use the editor. Basically,
we start a new voice, select synthesizer element 1 (we have 8 of them), and set
its waveform to the piano waveform that we just created. When we play the
keyboard, we should hear the Motif responding just like it did when we were
playing the waveform in the sampling mode. Now, we can use the amplifier
envelope generator to cause the samples to have a slight decay when we let go
of a key. We can use the filter settings to map key velocity to filter cut off,
so that playing the keyboard softer causes the filter to be slightly closed,
and therefore dull the sound.
We can add strings to the piano by enabling synth element 2, and setting its
waveform to one of the built-in strings waveforms.
If we wanted to get fancy, we can simulate the thunk when you release a piano
key by enabling a third element, selecting the built-in piano key release
waveform, and setting that element's XA control to trigger that element only
when a key is released.
You don't need to go through all of this to make a voice, though. If you're
trying to use stabs or one-shot samples, you can make waveforms with a single
keybank (in many cases the Motif will do this for you when you load the wav
file or sample directly from the Motif). If you want to make a voice, you don't
need to sample your own instruments and build your own waveforms, as the Motif
is bursting with waveforms that are ready to go. Unlike a lot of synths (like
Rolands), the Motif waveforms are recorded with out any effects. They're raw
recordings of the instruments, and it is up to the synthesizer settings in the
voice programming to make them sound like a particular instrument. For example,
there are only two sets of electric guitar samples in the XS, but they are
detailed sets that are made directly from the pickups of a guitar, and include
many velocity layers (dead notes, mute notes, three levels of open strings,
slap, harmonic tone, and slide). Every voice can process those same raw samples
through eqs, compressors, and amp simulators in order to get a specific tone.
Then, you still have enough effects power left over to add some big attention
grabber like delay, chorus, flanger, etc. This is more like how a guitar sound
is built in a studio. You start with a strat (Strat waveform on the Motif),
adjust the pickup levels and tone knobs on the guitar (element EQs), plug into
an amp (Motif amp sims), add stomp boxes or out-board mix effects (Motif insert
effects), and you have a guitar voice. One reason the Motif sounds so different
than other synths when simulating real instruments is because instead of having
two dozen different guitar samples, all fighting for memory, Yamaha gives us 2
very high quality sets of raw samples, and then gives us the tools to build our
own specific tone through the synthesizer engine.

Thanks. With the editors, are you able to set parameters on voices? If so,
would this include sample voices, once you've keygrouped them and assigned them
to user banks?
